KY-022 Arduino Code

The following Arduino sketch uses the IRremote library to receive and process infra-red signals. Use the KY-005 IR transmitter module to serially send data to this module.

Links to the required libraries for KY-022 Arduino example sketch can be found in the Downloads section below.

#include <IRremote.h>

int RECV_PIN = 11; // define input pin on Arduino 
IRrecv irrecv(RECV_PIN); 
decode_results results; // decode_results class is defined in IRremote.h

void setup() { 
	Serial.begin(9600); 
	irrecv.enableIRIn(); // Start the receiver 
} 

void loop() { 
	if (irrecv.decode(&results)) {
		Serial.println(results.value, HEX); 
		irrecv.resume(); // Receive the next value 
	}
	delay (100); // small delay to prevent reading errors
}
